Shudder in front when braking

[Pinkee]

Just wondering what i can do?
Heres the story: bout a month ago i did my fork seals in. and got a bit of oil on my disks. Replaced my seals, wiped off all of the oil (or so i thought). Since then i have had slippage in one spot on my front disks and under high speed braking. oh shit does it do the nerves in.

I know one of my options is skimming the disks to get rid of the glazing that has occurred. but being a poor student i cant afford it, are there any other ways to get rid of the problem?!?

cheers all!

have you wiped down your brake pads? I'm not very technically inclined when it comes to bikes, but I would think maybe there is some residual oil on the pads causing extra slippage?

try wiping the disks with a really strong solvent like meths or similar ( a few times ) and as Chookie said there will now be some shit on your pads too, Ideally change them but you could try cleaning them too.

Have the fork seals been repaired properly ?? Cause if the wrong grade or level of oil was put in this can affect your mechincal grip too...

Some bikes also have to have the caliperwheel aligned with feeler gauges so that the gap between the caliper and disk is correct.

I used "Brake and Parts Cleaner"from my dad's work on my brakes. It is used to clean the brakes on Elevators. Have had no trouble with them at all. Maybe you could try sourcing some from the store... It's in a gold can, fairly generic product.

when i bought my bike, it had oil all over the front pads and discs. i bought a can of brake cleaner (CRC brand) and gave them a good clean. i then replaced the pads, and gave the discs a bit of a rub with wet and dry (perpendicular to the rotation of he discs....) just to help clean the discs and run the pads in.
work like a damn charm!
could also mean you have warped discs or are in need of new pads.
you should always be a bit gentle at first with new pads, to prevent them glazing.
perhaps also give them a bit of a rub with some wet n dry

Man.. thats wierd u say that. Since o came off iv had the same problem..
But its not till the bike is just about to stop.. then it shudders? I wondered if it was like damp pads or somthing.. The bike still stops, just a strange shudder at the end of the braking.

Nick is it possible that one of your disks might have contacted the ground ?? If so then maybe it has got a slight run out in it.

is that goin to cost me ?

[Gordo]

if the disk is bent then yes, you can replace it or have it repressed.
Or live with the judder untill you sell it to some unsuspecting pom
